DSA-596-2 sudo -- missing input sanitising

Debian Security Advisory

DSA-596-2 sudo -- missing input sanitising

Date Reported:

24 Nov 2004

Affected Packages:

sudo

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 281665.
In Mitre's CVE dictionary: CVE-2004-1051.

More information:

Liam Helmer noticed that sudo, a program that provides limited super user privileges to specific users, does not clean the environment sufficiently. Bash functions and the CDPATH variable are still passed through to the program running as privileged user, leaving possibilities to overload system routines. These vulnerabilities can only be exploited by users who have been granted limited super user privileges.

For the stable distribution (woody) these problems have been fixed in version 1.6.6-1.3.

For the unstable distribution (sid) these problems have been fixed in version 1.6.8p3.

We recommend that you upgrade your sudo package.

Fixed in:

Debian GNU/Linux 3.0 (woody)
